I'd ilke to add the ability to test cl-unification by evaluating either of: (asdf:test-system 'cl-unification) (asdf:test-system 'cl-unification-test) The change involves adding one line: :in-order-to ((test-op (test-op :cl-unification-test))) to cl-unification.asd and adding the cl-unification-test.asd file below. Any objections? bob ========== ;;;; cl-unification-test.asd (in-package #:asdf) ;; Tests implemented using the ptester framework are run at *load* time, so ;; we tell ASDF that loading a file containing ptester code is never done. ;; This causes ASDF to run all the tests whenever ASDF:LOAD-SYSTEM or ;; ASDF:TEST-SYSTEM is called with argument CL-UNIFICATION-TEST. (defclass ptester-source-file (cl-source-file) () (:documentation "A Common Lisp source file containing ptester code.")) (defmethod operation-done-p ((operation load-op) (component ptester-source-file)) nil) (in-package #:common-lisp-user) (defpackage #:cl-unification-test-system (:use #:common-lisp #:asdf)) (in-package #:cl-unification-test-system) (defsystem #:cl-unification-test :depends-on (:cl-unification :ptester) :components ((:module "test" :components ((:ptester-source-file "unification-tests")))))
